Failed to expose service when an ambassador container already exists #200
Description
I have issues exposing the elasticsearch container on a remote server.
Here are the commands:
dokku elasticsearch:create es
dokku elasticsearch:expose es 127.0.0.1:9200 9300
The expose command produces this error:
docker: Error response from daemon: Conflict. The container name "/dokku.elasticsearch.es.ambassador" is already in use by container "b1648f0bded938e0e8deb5410484e352271e33dd73270549495dbaa9d3dfa5dc". You have to remove (or rename) that container to be able to reuse that name.
Still I try to run this command on my local machine to access the server using an ssh tunnel:
- ssh -o ExitOnForwardFailure=yes -f -N -L 9200:127.0.0.1:9200 "root@$SERVER_IP"
But the site http://127.0.0.1:9200/ still cannot be reached. I use similar methods to expose postgres and redis and they all work. No luck with elasticsearch.
This is the result of docker container ls. It looks like elasticsearch ambassador fails to be created.
